HOIST FOR HAND ING TANK-SECTIONS.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed February 9, 1905. Serial No. 244,851.

To all whom it may concern:

Be it known that I, DAVID O. PAIGE, of Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in I-Ioists for Handling Tank-Sections; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention relates to improvements in hoisting apparatus, and it has for its purpose to provide an apparatus of this kind which is particularly useful being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is an elevation of a hoisting apparatus constructed in accordance with my invention showing a tank section suspended in a horizontal position in full lines, the pivoted'position which it will subsequently occupy when turned being indicated in dotted lines. Fig. 2 is a fragmentary end view of the device shown in Fig; 1 indicating the relative positions of the tank section. Fig. 3 is a sectional view on the line 3-3 of Fig. 1 showing the locking bolts in section. Fig. 4 is a sectional view on the line 44 of Fig. 3 showing the cooperative engagement of the locking bolts and the rivet holes in the flange of a tank section. Fig. 5 is a sectional view on the line 55 of Fig. lshowing the locking device for securing the suspension members in adjusted positions on the supporting beam, and Fig. 6 is a detail view of another form of device constructed in accordance with my invention which is adapted to be used in connection with tank sections, the flanges of which have not been perforated.

The same numerals of reference in the several figures indicate similar parts.

An apparatus of the kind described constructed in accordance with my invention embodies in its present form a supporting beam 1 which is preferably composed of an I-beam which may be of suflicient length to enable bodies of the desired width to be suspended from it, and it is provided intermediately of its ends with an attaching ring 2, the latter being adapted to receive the usual hook of a suitable hoisting device.

In the manufacture of tank sections and similar bodies which are usually operated upon in different parts of the shop, it is preferable to use a hoisting crane which is capable of being moved into various positions, and in the present form of my invention I have shown a hoist of this kind which embodies a fluid pressure cylinder 3 having a suitable connection with a source of fluid pressure supply, and is provided with a controlling valve 4 by means of which a piston 5 which oper ates therein may be controlled, said piston being provided with a hook 6 to engage the ring 2 of the beam. This cylinder 3 is supported through the hook 7 from a carriage 8 which is mounted on rollers 9, the latter being arranged to travel along the track or support 10. On the beam 1 at either side of the supporting ring 2 are provided a series of spaced notches or apertures'll,

and over the lower flange of this beam in which these apertures are formed are the brackets 1212 which are arranged to slide longitudinally of the beam and are provided with locking devices for retaining them inthe desired adjusted positions longitudinally of the beam. This locking device in the present instance embodies a pin 13 which is arranged to pass through apertures in the bracket and through the apertures or, notches 11 in the beam to prevent relative longitudinal motion of the parts, a wire or other connection 14 being provided for preventing the loss of the pin 13.

From the brackets 12 are suspended the rods 15, and the lower end of each of these rods is attached to a swivel eye 16, and each of these eyes is pivotally connected by the pin 17 to the attaching devices for the tank sections. These attaching devices which are particularly adapted for use in handling tank sections which are provided with oppositely arranged peripheral flanges and which are to be employed on sections, the flanges of which have been perforated in the usual way to receive the belts or rivets which are to secure the tank sections together when they are assembled, embody in their present form a bar or member 18, one end of which is provided with one or more projections or extensions 19 which are formed to enter one or more apertures in the flange, and the opposite end of this bar is recessed as at 20 to receive the longitudinally movable bolts 21 which are normally operated upon by springs 22 which are inclosed within the bar 18 and rest behind each bolt, and to each of those bolts is attached a handle 23 which is arranged on the exterior of the bar and is connected to each of the bolts by the screws or pins 24, the latter operating in the slots 25 of the bar to enable the handle 23, and consequently each of the bolts 20, to be simultaneously withdrawn in a direction longitudinally of the bar. Fiach'of these bars 18 is of a length just sufficient to pass freely between the oppositely-arranged flanges of thetank section which are all approximately of uniform dimensions for tanks of a apertures in one of the flanges, and while the bolts 21 swung from a horizontal position into a vertical positionso that it may rest upon'its periphery and this is permitted by the pivotal connection between the swivel eyes 16 which are attached to the suspension rods 15 and the bars 18 of the attaching devices. In the same way the tank section may be lifted while it rests upon.

its periphery and then swung into a substantially horizontal position, and this is useful in facilitating the erection of the tanks, as it enables the different sections to be superposed in relative horizontal positions.

In order to enable tank sections or other objects of different diameters to be accommodated by the supporting beam, the brackets'12 are adjustable relatively to one another on the beam 1 and this will enable the attaching devices-to be suspended from the beamat the proper distance apart so that they can be easily applied to the object which is to be lifted or otherwise handled, the pins 13 operating to retain these brackets in their adjusted positions. In moving the brackets 12 longitudinally of the beam 1' they should be moved together and equally spaced from the center of the supporting ring 2, for it is-particularly desirable tomaintain the beam 1 in equilibrium. In handling tank sections the flanges of which have not been perforated, a clamp similar to that shown in'Fig. G'may be employed which is-attached by the swivel 16 to the suspension rod 15 in the usualway, and it comprisesa bar 26 which is provided at one end with an abutment 27, and opposite to this abutment is provided a clamping screw 28 which is arranged to operate-upon one of the flanges of the tank section to clamp it firmly against the abutment 27', and atthe opposite end of the bar 26'are provided the oppositely-arranged clamping screws29 and 30 which are arranged preferably in alinement, and are adapted to clamp the opposite flange of a tank section between them, the pivotal connection between the swivel 16 and the bar 26 enabling the tank section or other object to be handled in a manner similar to that hereinbefore described. By providing the relatively fixed abutment 27 at one end of this bar and the oppositely arranged adjusting screws 29 and: 30 at the opposite end thereof, variations in the distance between the flanges of the tank sections may be compensated for, and therefore the use of clamps of different sizes is unnecessary. An apparatus for hoisting and otherwise handling tank sections and similar objects is particu larly useful when these tank sections have been pro vided with a lining of enamel or other frangible material Which is liable to become damaged or otherwise injured should the usual method of attaching the crane or hoist to the objects be employed, for it will be obvious that the attaching devices are applied to the sections entirely at their outer surfaces, and in a way that Will not strain the sections when they are lifted, and in this way all danger of fracturing'or otherwise damaging the enamel is avoided, for it will be obvious that the 'ing devices: for permitting the latter to turn in to good advantage in lifting the tank section from a r horizontal position to enable it to be swung around and stood on its periphery in order that it may be readily 1 rolled into any part of the shop.
